Php SQL Injection (CVE-2026-26710)

Overview

A critical security vulnerability has been identified in the code-projects Simple Food Order System version 1.0. This flaw allows an attacker to perform SQL Injection, a technique where malicious code is inserted into database queries. The specific vulnerable component is the /food/routers/edit-orders.php file.

Vulnerability Explanation

In simple terms, the application does not properly validate or sanitize user input before using it to construct database queries. When the system processes requests to edit orders, an attacker can craft special input containing fragments of SQL code. The application mistakenly treats this malicious input as part of its legitimate database command, allowing the attacker to manipulate the query. This is akin to someone writing a command into a form field and the system blindly executing it as an instruction.

Potential Impact

The impact of this vulnerability is severe. A successful attack could lead to:

• Data Breach: An attacker can read, copy, modify, or delete sensitive data from the database, including customer information, order details, and potentially administrative credentials.
• System Compromise: In some cases, SQL Injection can be used to bypass login systems, gain administrative privileges, or even execute commands on the underlying server.
• Service Disruption: Attackers could corrupt or delete database tables, causing the entire ordering system to fail.

Given the direct path to the database and the high potential for complete system compromise, this vulnerability is rated as CRITICAL with a CVSS score of 9.8.

Remediation and Mitigation

Immediate action is required for any deployment of Simple Food Order System v1.0.

Primary Remediation:

1. Apply a Patch: Contact the software vendor (code-projects) immediately to inquire about an official security patch or updated version that addresses this vulnerability. Replace the vulnerable edit-orders.php file with the patched version.
2. Code Fix: If a patch is unavailable, the root cause must be fixed by modifying the source code. The solution is to use parameterized queries (prepared statements). This method strictly separates user-supplied data from the SQL command structure, making injection impossible. A developer familiar with secure PHP coding practices (using PDO or MySQLi with prepared statements) must implement this fix.

Immediate Mitigations (Temporary):

• Restrict Access: If patching is not immediately possible, restrict network access to the application (e.g., via a firewall) to only trusted IP addresses, such as those from your internal network or specific administrative locations.
• Web Application Firewall (WAF): Deploy or configure a WAF in front of the application to filter and block SQL injection attack patterns. This is a protective layer, not a fix for the underlying code.
• Monitor Logs: Closely monitor application, database, and server logs for any unusual or suspicious query activity.

General Advice: Discontinue use of unmaintained or end-of-life software. This vulnerability highlights the importance of using software from vendors who provide regular security updates and following secure coding practices for all custom development.
